Procedure

A solution of ethyl 3-amino-4,4-dimethyl-hexanoate, 27a, (0.24 g, 1.28 mmol), 2,6-dichloro-5-fluoro-pyridine-3-carbonitrile (0.29 g, 1.53 mmol) and Et3N (0.43 mL, 3.07 mmol) in acetonitrile (4.8 mL) was stirred at 70° C. overnight. The reaction mixture was concentrated in vacuo and purified by silica gel chromatography (10-40% EtOAc/Hexanes gradient) to provide 205 mg of ethyl 3-[(6-chloro-5-cyano-3-fluoro-2-pyridyl)amino]-4,4-dimethyl-hexanoate; LCMS Gradient 10-90%, 0.1% formic acid, 5 minutes, C18/ACN, Retention Time=3.75 minutes (M+H) 342.04.
